Hi Wolfgang, 

Thanks for answering my question.  I loaded the latest version of Debian
(yesterday) from their website (using the "live" version and then installing
from that image).  I searched the installation and didn't find sja1000_isa
at all, only sja1000 and sja1000_platform.  I have a 32 bit Atom board and
the Debian installation went normally.  Did I perhaps install the wrong
thing?  Thanks again for your patience!

I have in my Ubuntu distribution:

~$ ls -l /lib/modules/2.6.38-8-generic/kernel/drivers/net/can/sja1000/
total 72

-rw-r--r-- 1 root root  6516 2011-04-11 11:16 sja1000_platform.ko

If you just find sja1000 and sja1000_platform, your distro/kernel is
most probably broken.

Wolfgang.

Please excuse my ignorance, but I'm very new to compiling Linux kernels,
setting parameters for Platform type drivers etc.   Our Intel Atom based
board has an SJA1000 controller on it that worked in older versions of 
Linux (such as Ubuntu 10.04) with the SJA1000_ISA driver that was 
included with Ubuntu.  Unfortunately, with Debian Squeeze (the latest 
version), it seems that this driver has been replaced with 
SJA1000_PLATFORM.  However, unlike

Why do you think that? The sja1000_isa is still available in the mainline
kernel. And the sja1000_platform driver is not replacing it? It serves a
different bus. Is it possible that you switched to 64bit Linux at the same
time? Older kernel versions do not support sja1000_isa on
x86_64 but the issue has been fixed in the meantime.

Wolfgang.
